There is a bug in the LaserWriter IINT ROM that causes this. If you have a
piece of paper in the manual-feed tray when you issue a manual-feed print
job, the status light stays on after the print cycle. The workaround is to
send the manual-feed print job, then wait until the status light is
blinking before you insert the piece of paper.
There is no other workaround for this problem, and none is planned because
it is a cosmetic problem and does not affect the actual operation of the
printer.
